[Gumstix-users] Problem with musb_hdrc

[Robert V. IV <ro...@io...>]

Hi,

I have a high-speed hub (tested & working with computer) wired to OTG+
and OTG-, with USBOTG_ID shorted to ground.  I am not seeing anything
regarding detection of my hub and devices, even if I power cycle them
while they are connected.  I've used the NAND and the most recent
console image on microSD.  This is my dmesg output (grep usb):
